Abstract (en)
The present invention provides a vehicle travelling control apparatus for a vehicle with an HST (10) and a mechanical transmission (30), which are connected in tandem to each other and interposed in a travelling power transmission path between a driving power source (200) and driving wheels (210). The vehicle travelling control apparatus includes a speed-change control mechanism which in turn includes a signal detection part (110) and a control part (150) for controlling the changing of the output speed of the HST and the shifting operation of the mechanical transmission. The signal detection part (110) includes a load-torque detection means (111) for detecting the load torque with respect to the vehicle. The control part (150) is designed to control the mechanical transmission and the HST based upon the detected results by the load-torque detection means (111) so that where the vehicle lies in a high load torque state, the control part (150) downshifts the mechanical transmission to a lower speed stage, while increasing the output speed of the HST. <IMAGE>
